BEETLING-MACHINE.

T0 all whom t may concern Be it known that we, HARRY TAYLORv MnnsDnN andFREDERICK Jnnvrs, subjects of the King of Great Britain, residing atHigher Broughton, and Burnage, respectively, in the county of Lancaster,England, have invented certain new and useful Improvements inBeetling-lfachines; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relat-es to improvements in that type of beetling machinesin which the beetling hammers are driven toward the beetling roller andwithdrawn from the same by means of a compressed fluid acting upon apiston formed on each hammer or beetling rod, and arranged in acylinder, the movement of the said piston being cont-rolled by a valvearranged to be operated from a moving part of the machine, or by thepiston which it controls, the pressure of the blows given by the saidhammer being regulated by altering the pressure of the compressed fluid.

The object of our invention is to provide a construction of beetlingmachine which is more reliable and eilicient than hitherto has been thecase. To this end we provide improved means for operating each valve bythe movement of the hammer which it controls or by the said compressedfluid; moreover we provide means in the beetle head cushioning the saidblow by the aid of the said compressed fluid, and means for rend-eringany one or more of the hammers inoperative as desired. We attain theseobjects by the mechanism illustrated in the accompanying three sheets ofdrawings, in which- Figure l is a detached sectional side view, and Fig.2 a front view showing one embodiment of our invention. Fig. 3 is adetached sectional side view of a modification. Fig. l is an enlargeddetached front view, and Fig. 5 an enlarged detached sectional side viewof a detail of construction. 6 is an enlarged detached side view andFig. 'E' an enlarged detached front view of another detail ofconstruction.

Similar letters refer to similar parts Vthroughout the several views.

In carrying out our invention the said compressed air or other fluidsource may consist of a compressor which may be situated in any desiredposition, preferably near the Specification of Letters Patent.

main engine or boilers, to save transmission of power losses. Thecompressed air, or other fluid under pressure is brought to the machinein pipes, or by any other suitable means. The regulation of the blow maybe obtained by means of a variably loaded pressure chamber (like agasometer) between the machine and the generator of the Huid pressure.

Referring now to Figs. l and 2, each hammer a is attached by suitablemeans to a piston o working in a cylinder o, or other suitable chamber,closed preferably at each end, and each end of the chamber is connectedby pipes CZ, e, or by any other suitable devices, to one or more valvesf to an eX- haust pipe g or receptacle, and also to the supply pipe 71,or receptacle (not shown).

The hammers e are connected to the valve or valves f" by connecting rodsz' which are so made as to be readily detachable, see more particularlyFigs. 6 and 7, each moved by a piston o and all working on a commoncrank shaft 7c; the cranks may be formed on the shaft at any desiredangle to one another, and the valves f accordingly arranged to work inharmony with the said cranks. The crank shaft 7c drives onto anintermediate shaft Z by means of a chain drive and the intermediateshaft actuates each valve or set of valves f, also by means of a chaindrive. The chain wheels on the intermediate shaft Z are mounted on clawcouplings which `are so arranged that they can only enter into gear inone position so as not to disturb the setting of thevalves when thrownin and out of gear, see more particularly Figs. 4t and 5. By this meansthe valve may be stopped when required while therest of the machinecontinues to work. Each valve f has tWo passages which are so arrangedas to bring the exhaust and compressed air supply alternately intocommunication with the opposite ends of the cylinder c.

Each hammer a is actuated by its valve or valves f in the followingmanner.: The valve or valves y are in such a position that one end ofthe cylinder c receives fluid pressure, while at the same time the otherend of the chamber c is open to exhaust g. Thus the piston. o and hammera are propelled, and strike a definite blow. rlhis motion of the pistonb is transmitted to the valve o-r valves f by the above described deviceand reverses the position of the said passages thereby opening the firstmentioned side of the cylinder c to exhaust and cutting iiuid pressureoff from the same and closing the second mentioned side of the cylinderto exhaust and opening the saine to the fluid pressure, thus bringingthe piston l) and hammer a back to the starting position for anotherblow.

The striking'portion of the hammer a is provided with a fluid orpneumatic cushion to give a resilient blow, for example of the formshown in Figs. l and 2. The hammer u comprises a chamber m in which apiston 'a works. rThe piston a is provided with a striking piece o ofany suitable material. The piston a receives its fluid pressure on therequired side, by for instance, a passage 7? in the piston 7) and hammerrod r and non-return valve q.

To prevent noise, shocks, or brealmgcs, springs or pads of rubber, orother suitable material may he used where required.

il' hen the main valve or other suitable regulator is opened, thepressure of the compressed fiuid accomplishes the work and at the sametime controls the machine.

1When designing the machine, by setting` the cranks at the necessaryangle to one another and arranging the setting of the valvesaccordinglv, the hammers o may be caused to strike in any order, and atany time which the user of the machine may desire. 1f any hammer orhammers are not required to worlt owing to the varying widths of cloth,the supply of air, or other fluid, may be cut olf from them by anysuitable means, such as for instance valves, or cocks s, which may besuitably connected to hand levers t arranged to move a supporting pieceu for holding the respective hammer or hamm-ers out of action and tosimultaneously throw out the claw coupling of the chain wheel drivingthat particular valve and the connecting rod z' may also be uncoupled,see Figs. G and 7.

The cloth may be wound upon beams '0, or may be in flat folds placedunder the hammers on a surface plate for flat beetling, as in the oldwood faller types.

Any convenient means may be employed to traverse and rotate the beams asrequired and may be actuated by the power of the fluid, that is a fluiddriven engine may be used to do this work.

rilhe speed of the machine, that is the number of blows per minute madeby each hammer, is controlled by any suitable, adjustable automaticgovernor. Any convenient and suitable lifting tackle may be employed ifnecessary to lift the beetling roller or surface plate according to thetype of machine used, that is to say, flatbeetling machine or rollerbeetling machine.

vWhen using compressed air, the same may be cooled before reaching` themachine by ment, such as for example, a coiled pipe immersed in coldwater.

To prevent any damage when the machine has to be stopped, both ends ofall the cylinders c may be arranged with exhaust valves (not shown)which may be opened before the main valve or other suitable regulator isshut.

fr suitable guide for example as shown on the drawing is used to preventthe hammers from turning.

According to a modification, and referring to Fi 8, in lieu of operatingthe valves f by the movement of the piston Z) in the cylinder c, we mayprovide an independent piston w and cylinder a', which may act by meansof the connecting rod lQ/ on an intermediate shaft Z or directly on thevalves f. in this case the piston vw would be driven by the motivefluid, admitted to the cylinder by a valve actuated from any suitablemoving part of the machine and controlled by a governor of the usualtype. The hand levers t in this instance depend and the slides .e aresituated below the cylinders, as shown in Fig. 3, or in any convenientposition. Springs 2 may be provided or a small amount of the motivefluid may be locked at each end of the cylinder by the setting of thevalves in order to cushion the pistons and so prevent dan'iage, or bothmeans may be employed.

The hammers are capable of being placed in any desired relativepositions to the cloth, that is either above the cloth and strikingdownward, or below the cloth and striking upward, or at any other angleor position as desired.

rihe traverse and rotating motions of the beam on which the cloth isbeing bectled, and

the rotating motion of the beam on which the cloth is being placed forbeetling` when ready, may also be accomplished by utilizing the motivepower of the compressed fluid, thus obviating the necessity for anytransmission of power by gearing, shafting, pulleys, or other means,from the main engine, other than the fluid pressure in the shape ofcompressed air, or other fluid or steam.
